ZORBZ are the world's first self-sealing water balloon with Snap and Seal technology. That means you no longer have to tie before you throw, ever again! Since you don't have to stop to tie, Orbs make it easier for you to soak your opponent and splash your way to hero status. How fun is that? The days of tying are over! This works by placing the neck of the Orbs water balloon on the filler nozzle, slowly filling the Orbs water balloon while holding it in an upright position, until it is about the size of an orange. Next, just simply remove Orbs from the filler nozzle by gently pinching the neck, hold the balloon upright, slightly stretch the neck, let go of the neck and allow Snap and Seal technology to seal the balloon without having to tie it. Its that simple! Orbs seal instantly so playing with water balloons twice as easy with double the fun! Orbs 00503-3 Seal-Sealing Water Balloon package include 100 water balloons and 1 filler nozzle. Orbs are proudly made in the USA. What are you waiting for? Stop Tying and Start Winning! It is highly recommended that adults should always be present when Orbs are being used for children under 8.
